Research Assistant in Spatial and Single-cell omics of Human Adipose Tissue

Do you want to contribute to top quality medical research?

The Rydén & Mejhert laboratory is a multidisciplinary research group of 15–20 members, including postdoctoral fellows, PhD and master’s students, and technical staff. We are equipped with state-of-the-art infrastructure, encompassing a comprehensive preclinical laboratory at Biomedicum and a dedicated clinical research unit at Karolinska University Hospital, Huddinge. Using these resources, we focus on understanding how alterations in human white adipocyte function contribute to cardiometabolic disorders, including type 2 diabetes, dyslipidemia, and atherosclerosis.

Your mission

We are recruiting a research assistant to lead a project investigating adipose tissue alterations across diverse metabolic context, using well-characterized human cohorts. The project builds on adipose tissue biopsies collected within a large population-based study linked to extensive clinical phenotyping and detailed fat cell characterization performed ex vivo.

The aim is to understand how metabolic disease influences adipose tissue organization, cellular composition, and gene regulatory programs. The successful candidate will apply spatial transcriptomics and single-nucleus RNA sequencing to human adipose tissue biopsies to investigate cytoarchitectural features and cell-type specific changes associated with disease progression.

These molecular datasets will be integrated with deep clinical data and functional adipocyte measurements to define tissue-level alterations across different metabolic profiles. The project combines human physiology, tissue biology, and high-dimensional molecular profiling, thereby contributing to a deeper understanding of disease mechanisms in cardiometabolic disorders.

This position is embedded in a vibrant and interdisciplinary research environment with strong links to clinical studies and translational metabolic research, offering excellent opportunities for scientific development, collaboration, and career advancement.

This is a 6-month position, with the possibility of an extension for an additional 6 months.

Your profile

The ideal candidate has a strong interest in human adipose tissue biology and metabolic disease and is motivated to work with clinically anchored human material. The applicant should be comfortable generating and analyzing complex datasets and have experience with advanced molecular or omics-based techniques.

Experience with spatial transcriptomics, single-cell and/or single-nucleus RNA sequencing, or related technologies is highly desirable, though not strictly required. Familiarity with analysis of transcriptomic data, including work in R, Python, or similar environments, will be considered a strong asset. The key requirement is the ability to take ownership of data generation and carry out thorough and independent downstream analysis.

The candidate should be able to work independently, manage complex projects, and collaborate effectively in an interdisciplinary research environment. Strong analytical thinking, attention to detail, and the ability to critically evaluate data are essential. Intellectual curiosity and an interest in integrating molecular data with clinical and physiological phenotypes are important for success in this role.

Proficiency in written and spoken English is required for effective communication, manuscript preparation, and collaboration within an international research environment.
